List of the band numbers corresponding to each band in the image

  • IR images have 1-10 bands available
  • VIS images have 1-5 bands available

Yaw angle

A non-zero value indicates spacecraft rotation during image collection; for the ODY spacecraft, a positive yaw angle indicates a right hand rotation around the spacecraft nadir vector.

Roll Angle

A non-zero value indicates spacecraft rotation during image collection; for the ODY spacecraft, a positive roll angle indicates a right hand rotation around the spacecraft velocity vector.

Spacecraft Pointing Mode

Odyssey pointing mode during image collection; most common modes are NADIR and OFF-NADIR. See ODY Orientation & Pointing for a full description of all valid modes.

Spacecraft Orientation

Odyssey orientation during image collection; described as an angle (in degrees) of rotation away from nadir around the three axis spacecraft frame of reference (PITCH, ROLL, YAW). See ODY Orientation & Pointing for more information.
